I just noticed that Gigabyte has posted yet another CPU microcode update BIOS for my motherboard. (Z170X gaming 5)
My understanding is that microcode updates are classified by Intel. (They don’t usually say what they fix, why they are issued, or even how microcode updates are applied) They are issued to address defects (“errata”) found in a CPU. So, I know we won’t get any info on this.
I’m just surprised to see yet another microcode update so soon after the Skylake launch. Makes me wonder if maybe all is not well with Skylake, and maybe this could explain the supply shortages of most of the Skylake chips?
